Well, that’s a little vague and I’m not sure exactly what the problem is but let’s go with their suggestion to reset your ip address. There are two IP addresses at play here. The first is the one given to you by your ISP. Time Warner, ATT, etc... You can find that by going to www.whatismyip.com. The only way to attempt to get a different IP address is to unplug your modem then re-power it. Depending on your ISP, you may get a new IP or your may get the same one. It really depends on the area activity as well as other things.

To reset your actual IP address given to you by your router...this is called your sub network IP address. Depending on the router’s settings, it may be giving out 192.168.x.x numbers or 10.0.1.x if it’s an Apple Router. You can:

go to system prefs/Network.
Select the Airport (if wireless) in the left hand column then select “Advanced”.
Now select TCP/IP
Make note of your IP address then choose to Renew DHCP lease.

It’s very likely you may get the exact same number. There are several ways to go here. You could set your sub network IP address manually or your could go to your router’s settings and address the problem there. There are many choices.
